We may chalk it up to good fortune that the following words never needed to be spoken: In their exploration, they stirred the people of the world to feel as one; in their sacrifice, they bind more tightly the brotherhood of man. It all sounds so simple and straightforward, which obscures the real truth: for every one of these steps, there were hundreds (or more) potential points of failure that everyone involved needed to guard against. Apollo 11: 50 Years Later On Jan. 9, 1969, NASA announced the prime crew of the Apollo 11 lunar landing mission. One is the Command Module; the other is the Service Module. Three days after leaving the Moon, on July 24, 1969, they splashed down in Earth's oceans, successfully completing their return trip. Fortunately for everyone, none of the debris resulting from the Service Module's re-entry impacted the Command Module, and the astronauts all arrived safely back on Earth.

Columbia and Eagle now reunited to become Apollo 11 again. If it failed, it would lead to certain death, similar to the demise of the Soviet cosmonaut Vladimir Komarov. The plan to avoid it was simple: the Service Module, post-separation, would perform a series of thrust maneuvers to take it safely away from the re-entry path of the Command Module.

Opinions expressed by Forbes Contributors are their own. On July 20, the Eagle (lunar module) undocked from the Columbia (command and service module), made a powered descent, and landed on the Moon's surface. Had those two modules collided, the astronauts on board would have had a failed re-entry, killing all three passengers. Apollo 9- Destroyed in Earth's Atmosphere. The Lunar Module, completely intact before the ascent stage is launched, can be seen in full beside the planted American flag. If Armstrong and Aldrin — the first two moonwalkers — were to perish before returning to Earth, the United States already had a presidential address drafted for such a purpose.

Apollo 11 was the spaceflight that first landed humans on the Moon.Commander Neil Armstrong and lunar module pilot Buzz Aldrin formed the American crew that landed the Apollo Lunar Module Eagle on July 20, 1969, at 20:17 UTC (14:17 CST).Armstrong became the first person to step onto the lunar surface six hours and 39 minutes later on July 21 at 02:56 UTC; Aldrin joined him 19 minutes later. This was to be the third crewed Apollo mission to land on the Moon, but was aborted due to the onboard explosion. “The Eagle,” aka LM-5, was the one used during Apollo 11, the mission that first sent men to the Moon. I have seen an Apollo 11 photo of a bag of equipment that was tossed out of Eagle to the surface and sitting in front of quadrant 1.

An ablative heat shield on the outside of the Command Module protected the capsule from the heat of re-entry (from space into Earth's atmosphere), which is sufficient to melt most metals. Continuing to monitor this 27th lunar orbit for the two-way communications between the two spacecraft. With the original flaw, the thrusters fired in a pattern that put the Command Module at risk. At the danger of becoming complacent, this step, in many ways, already seemed like old hat to many of those staffing the Apollo 11 mission. never reached the Moon. The launch and this one corrective burn were so successful that the other three scheduled SPS maneuvers were not even needed. That is the disintegrating Service Module. I am a Ph.D. astrophysicist, author, and science communicator, who professes physics and astronomy at various colleges. But these men were the first, and they will remain the foremost in our hearts. Humanity's first landing on the Moon occurred July 20, 1969, as the Lunar Module code-named "Eagle" touched down gently on the Sea of Tranquility on the east side of the Moon. The LM landed at 20:17:40 UT (4:17:40 p.m. EDT) on 20 July 1969 in the region known as Mare T… Communications are somewhat scratchy with Apollo 11. Without implementing the correct procedure for firing the various jets implemented, the safe return of the Apollo 11 astronauts would have to come down to luck. By shifting the Service Module to a significantly different trajectory, it wouldn't even re-enter at the same time as the Command Module, but would skip off the atmosphere this time. keep their feet out of the dust that covered the floor. on the porch, the Lunar Module Pilot  pushed the jett bag into The LM descent engine fired for 30 seconds at 19:08 UT, putting the craft into a descent orbit with a closest approach 14.5 km above the Moon's surface. a jett bag at the end of each EVA to Uncovered by Nancy Atkinson in her new book, Eight Years to the Moon, this anomaly could have led to a disastrous ending for astronauts Armstrong, Aldrin and Collins.

But of the innumerable things that could go wrong, one of them was entirely unexpected: the possibility that the Service Module, scheduled to break apart and safely burn up in Earth's atmosphere, could accidentally have a piece of its debris collide with the Command Module, ruining re-entry and killing the returning astronauts on board. In the aftermath of Apollo 11, investigators determined that the proper procedure for avoiding contact would be to properly time the firing of both the roll jets and the Minus X jets, which would lead to a 0% probability of contact between the two spacecrafts. (AFP/Getty Images), July 24, 1969. into Only July 17, the first thrust maneuver using Apollo's Service Propulsion System (SPS) was made, course-correcting for the journey to the Moon. The Command Module then re-enters the Earth's atmosphere, before finally parachuting down to land in the ocean. The Command Module then separates from the Service Module, which jettisons its fuel and accelerates away. The re-entry of the Service Module should have only come much later, after performing another orbit (or set of orbits) around Earth. The astronauts might not have successfully returned to Earth, however, if the procedure used to jettison the fuel from the Service Module had let it come into contact with the Command Module.

Once safely away, the Command Module would re-orient itself so that the heat shield was in the forward-facing position, prepared to absorb the brunt of the impact of re-entering Earth's atmosphere while protecting the astronauts inside.

On each mission except Apollo 11, an additional jett bag was filled prior to PLSS jettison and went out the hatch with the backpacks. (AFP/Getty Images). In the cramped LM cabin, a The astronauts might not have successfully returned to Earth, however, if the procedure used to jettison the fuel from the Service Module had let it come into contact with the Command Module. The Apollo 11 Command Module, "Columbia," was the living quarters for the three-person crew during most of the first crewed lunar landing mission in July 1969.

Even from our perspective in 2019, 50 years later, humanity's achievements from July, 1969, still mark the pinnacle of crewed spaceflight. This might seem like an extremely small point — to have the Minus X jets cut out after a certain amount of time firing as well as the roll jets — but you must remember that the spacecraft is full of moving parts. Apollo 11 Jettison Bag On The Moon is a photograph by Nasa/science Photo Library which was uploaded on November 24th, 2019. Chosen as the mission to fulfill then-President Kennedy's goal of performing a crewed lunar landing and successful return to Earth, the timeline appeared to go exactly as planned. And on July 24, re-entry procedures were initiated, returning the Apollo 11 crew to a safe splashdown in the Pacific Ocean. To quote from Nancy Atkinson's book, pilot Frank A. You can see the bits flying off. This is Apollo Control. Inside, you'll find many additional details about this event, including interview snippets with Gary Johnson himself.
